software
The demonstration software, preloaded in the board Flash memory, uses the built-in I
DD
measurement feature to automatically measure and display the MCU consumption on the
LCD (in Run and Low-power modes).This software also allows to demonstrate touch
sensing functionalities such as linear touch sensor or touchkeys.

3 Features
The 32L152CDISCOVERY offers the following features:
•
An STM32L152RCT6 microcontroller (256 Kbyte Flash memory, 32 Kbyte RAM,
8 Kbyte data EEPROM) in a 64-pin LQFP package
•
On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone
ST-LINK/V2 (with SWD connector for programming and debugging)
•
Board power supply: through USB bus or from an external 3.3 or 5 V supply voltage
•
External application power supply: 3 V and 5 V
•

current measurement
•
LCD
–
DIP28 package
–
24 segments, 4 commons
•
Four LEDs:
–
LD1 (red/green) indicating USB communication
–
LD2 (red) indicating that 3.3 V power supply is ON
–
Two user LEDs, LD3 (green) and LD4 (blue)
•
Two pushbuttons (user and reset)
•
One linear touch sensor and four touchkeys
•
An extension header for LQFP64 I/Os for quick connection to prototyping board and
easy probing
The STM32L-DISCOVERY offers the same features except an STM32L152RBT6
microcontroller (128 Kbyte Flash memory, 16 Kbyte RAM, 4 Kbyte data EEPROM) in a 64-
pin LQFP package.
